It was made out of waste items from the juice-producing industry, she said.

These included atoms found in orange peels and normally happening oils in avocado skins.

"The item is completely biodegradable, minimal effort and has preferred water holding properties over business SAPs. The main assets required in the making of the 'orange peel blend' were power and time, no extraordinary hardware nor materials were required," Ms Nirghin included her online accommodation.
